When I was using windowsXP I encountered a file manager called UltraExplorer http://www.mustangpeak.net/ultraexplorer.html that appeared really impressive.

Now in the Linux/UNIX world I was pointed towards a similar idea called 4Pane
http://www.4pane.co.uk/

I'm surprised to do a search on this forum and find almost nothing on 4Pane or the likes.
Is it a matter of preference simply? or are there other reasons for not using multi-pane file managers?
Just curious

(I'm using Sabayon-Gentoo at present but plan to go back to Ubuntu and Xfce because it's more newbee-friendly)
